Display virtual datacenter networks

To display the networks available to a virtual datacenter:

1. Go to Virtual datacenters → select virtual datacenter → Network.

• The default network is highlighted with a star symbol

• A network with an internet gateway is highlighted with a globe symbol

• In public cloud, to synchronize networks and IP addresses, click the round arrows synchronize button

• In AWS, you can filter the list of private networks by Availability Zone

You can display an inventory of your cloud networks easily in Virtual datacenters view

Open

Private networks in private cloud

Open

Private networks in public cloud (AWS)

In the Networks list, to view the pool and allocation of IPs:

• To display all the IPs in the virtual datacenter, click the All button at the top of the list

• To display the IPs in a network, click the Network name

You can then:

• Use the slider at the bottom of the list to move through the pages 

• Filter the list by entering text in the Search box. The filter works with all the columns of the table including:

  • IP Address

  • MAC address

  • Network name

  • Virtual appliance using the IP

  • VM using the IP

  • Provider ID of the entity using the IP (for example, a load balancer)

Edit a private network

To edit a private network

1. Go to Virtual datacenters and select a virtual datacenter, then go to Network

2. Select Private and select the network

3. Click the pencil edit button below the Networks list

4. If there are no VMs deployed in the network, you can change the Name, Gateway, Static routes, and make the network the new default for the virtual datacenter

   1. The gateway must be an IP address inside the range defined by the network address and the network mask

5. Optionally, change the DNS settings. The new settings will apply to all VMs deployed after you save the network

6. Click Save

Delete a private network

You can delete a private network if no VMs are using its IPs and it is not the default network for the virtual datacenter.

To delete a private network:

1. Go to Virtual datacenters and select a virtual datacenter

2. Go to Network → Private

3. Select the network and click the delete button below the networks list. 

Display onboarded external networks

The platform automatically onboards external networks when you onboard virtual datacenters from vCloud Director.

To display onboarded external networks

1. Go to Virtual datacenters → Network

2. Select a vCloud VDC

3. Go to External

Delete an onboarded external network

If an onboarded network has been deleted in the provider, its name will display in light gray text. If a VM is using an IP from this network, then you cannot deploy the VM.

If there are no VMs using the IPs of an external network that was already deleted in the provider, to delete the network in the platform, select it and click the delete button.

Set the default network for a virtual datacenter

Each virtual datacenter requires a default network. If you deploy a VM without assigning a NIC, the platform will add one from the default network. You cannot unselect the default network, instead you must assign a new default network to replace it.

To set a network as the default, you will require privileges to access this network in the virtual infrastructure.

To assign a network as the default for a virtual datacenter do these steps:

1. Go to Virtual datacenters → select virtual datacenter → Network → network type, e.g. Private

2. Create or edit a network

3. Select the Default network checkbox 

   • This default will override the platform default network and any network set for the enterprise in the datacenter

   • The new default network will apply to all VMs deployed after you set it

   • For a public network that is the virtual datacenter default, obtain IP addresses for your VMs before you deploy

Obtain IP addresses from public networks

See Obtain public IP addresses.

Synchronize public IP addresses with the cloud provider

To onboard any public IP addresses that were already created in your cloud provider, or update changes made directly in the provider:

1. Go to Virtual datacenters → select a public cloud virtual datacenter

2. Go to Network → Public

3. Click the double arrow synchronize public IPs button (beside the + add button)

Release a reserved public IP address

You can release a public IP if it is not assigned to a VM.

In private cloud, to release a public IP that belongs to a public network, select the IP in the IP list and click the delete button.

In public cloud, click the link to Remove from VDC and then click the delete button.

In private cloud with NSX-T, you can delete network resources by deleting the virtual datacenters. The platform will automatically remove VMs, virtual appliances, load balancers, public IPs, and firewalls from the virtual datacenter. The firewalls will remain in the enterprise and you can reuse them. When you delete a virtual datacenter, public IPs that are not used by VMs will remain in the provider and the synchronization process will delete them.

Limit network bandwith with QoS

You can limit network bandwidth of public IPs and for VDCs with NAT networks. For more details see the following documentation.

• Limit bandwidth of public IPs with QoS

• Manage NAT QoS

Reserve private IPs

Administrators can reserve private IP addresses so that users cannot work with them in the platform.

See Reserve private IPs.
